One of the features of the arrival of the NEQ regime reported in previous studies is the radiation of internal gravity waves [1]}, [2]}, [3]}.
In these spheroid wakes, we find that the integrated wave flux remains negligible compared to the other terms in the TKE budget and hence is not shown here. The small magnitude of the turbulent wave flux is consistent with the findings of [4]} who found that the magnitude of the wake-generated waves depends on the body drag coefficient – and the 6:1 spheroid has a very low drag compared to bluff bodies.
